Total Pressure (Pt), in the context of aircraft design and aviation, represents the sum of static pressure and dynamic pressure. It is often measured using a Pitot tube, which is a device that faces into the oncoming airflow to capture the total pressure.
The formula for total pressure is:
- Pt is the total pressure.
- Ps is the static pressure, which represents the pressure of the undisturbed air surrounding the aircraft.
- q is the dynamic pressure, which is related to the aircraft’s motion through the airÂ
